520 |a"Narrow Lake is a small, deep, clear lake of significant recreational value, located 140 km north of Edmonton, Alberta. Low phosphate and chlorophyll levels are indicative of a mesotrophic lake, in marked contrast to the highly eutrophic character of most prairie lakes. Remarkably, the bottom sediments have the phosphorus content of low-grade fertilizer. Iron-rich groundwaters seeping into deeper water cause precipitation of phosphorus and deposition to the sediments, rendering the phosphorus unavailable for algal growth. This natural control of trophic level by iron suggests that steel mill pickle liquor waste could find application in lake restoration"--Management Perspective.
